The SOS button or GPS locator is a function integrated into the phone or a separate device that, when pressed, sends a message with a warning or current location to predefined devices.

A mobile phone is considered shockproof if its design can withstand higher mechanical stress. Its manufacturer usually states from which height the phone can fall without damage, but detailed conditions of impact resistance of individual models may differ.

A mobile phone is water resistant if it meets a certified level of durability that allows total immersion. When it comes to mobile phones, it is the specification of the IP67, IP68, or IP69 Ingress Protection rating.

IPS, or In-Plane Switching, often also known as Super TFT, is a type of LCD display technology. It offers an excellent quality-price ratio, natural colours, low power consumption, and wide viewing angles up to almost 180 degrees.

NFC (Near Field Communication) is a wireless communication used to establish a connection between portable devices, over a very short distance, only up to 4cm. Previously, NFC was used to transfer photos and videos, but you'll often hear about it in connection with contactless payments.

LTE (Long Term Evolution) marks the next generation of mobile data networks. This is an intermediate step between 3G and 4G. Although manufacturers and operators sometimes mistakenly refer to it as 4G, it is not a full 4G network. That's for LTE Advanced. The maximum theoretical data transfer rate is up to 175Mbps for download and up to 57.6Mbps for sending data in one frequency band. 

NanoSIM is the smallest, most advanced type of SIM card.

A legújabb USB-csatlakozó a Type-C jelölést viseli. Az előzőektől eltérő alakjának köszönhetően mindkét oldalról be lehet dugni, azonban ez a USB 2.0 és USB 3.0 / 3.1 portokkal való visszafelé kompatibilitás rovására megy. Az adatátviteli sebesség eléri a 10 Gbit/s-ot.

A digital compass (magnetic sensor) detects the earth's magnetic field to determine the cardinal points. This enables the phone to correctly rotate the map to fit your orientation.

An ambient light sensor that monitors the ambient light levels and dynamically adjusts the display backlight intensity. A practical and handy feature, it is part of most modern phones. It turns the display brightness to the maximum in bright sunlight and dims the backlight in the dark.

Az Android a Google által kifejlesztett operációs rendszer, amelyet jelenleg a legtöbb mobiltelefon-gyártó használ. Ez egy nyílt operációs rendszer, amely gyakorlatilag korlátlan testreszabási lehetőségekkel rendelkezik. Egyes módosítások az alapbeállítások segítségével végezhetők el, míg más módosítások bármikor letölthetők a Google Play áruházból. A felhasználó így nagyon könnyen módosíthatja nemcsak a grafikus felületet, hanem a telefon kezelésének módját is. Az Android gyenge pontja a rosszindulatú támadásokra való nagyobb fogékonyság. Az egyes operációs rendszerek részletesebb leírása, előnyeik és hátrányaik a Mobil operációs rendszerek összehasonlítása című cikkben található.

Pure Android is an operating system for mobile phones with Android in its simplest form - it does not include an adjusted graphical interface or any features that are added to the operating system expansion by the individual manufacturers.
